Visual Description

Oh, Cast Hourglass! If you thought other Level 6 puzzles such as Vortex or Enigma were difficult — you will definitely find this 4-piece beast a challenge. Hourglass definitely outs most other Hanayama puzzles to shame in terms of difficulty and complexity. It is a true epitome of puzzler’s dream.

It is executed in great matte metal. The piece resembles the Hourglass model, hence it’s name.

The design itself is solid, mathematically calibrated, even, with parts and the model as a whole being symmetrically executed and that gives the piece a superb aesthetic feel.

Main Features

The model will take hours to take apart. Due to the number of pieces (4) it will take many moves and backtracking to progress.

I have counted 4 principal stages of disassemble progress with every stage counting 5-10 moves. To figure all of them out one will need a lot f patience and a great deal of logical thinking.

Although the assembled model is quite solid — 4 parts separately are not so it is very important not to apply too much force in case you get stuck — there are reports of people breaking this puzzle.

Certainly a champion of Hanayama puzzles, the last boss or the ultimate challenge, the Excalibur. But, to be completely honest, I do no want to be overly dramatic with this — the puzzle is really great and Jin Hoo Ahn proved to be one of the most prominent puzzle makers of our time.

Even if you think it might be to hard for you — it must be your duty to try it out to see if you are the one who can defeat it.
